Review of minutes from the last meeting

We went over the minutes from the meeting on November 29th.

Issues on GitHub

There were no new issues other than the ones noted above.

Sean mentioned an emerging issue with timing for CPP. Sean asked Elton Smith for a sample of signal Monte Carlo (μ pairs were provided) to work out the timing calibration procedure without use of the start counter. Some development was needed to get everything working. And yet, after calibration constants are applied, the vast majority of events show a 4 ns offset from the correct RF time. He is waiting for feedback from Elton and Simon, but this may show up as an issue in the future.
